( F )5.There are twenty-six letters in the Alphabet.
1、长方体的长、宽、高之比是4：3：2,棱长的总和是108厘米,求这个长方体的体积.
设长宽高分别为4x 3x 2x
(4x+3x+2x)x4=108
x=3
4x=12 3x=9 2x=6
体积为 12x9x6=648立法厘米
2、计算：35°41′30〃+24°18′35〃
=60°5〃
3、B、C两点把线段AD分成2:3:4三部分,M是线段AD的中点,CD=12厘米,求（1）MC的长；
由已知可得 AD=12÷（4/9）=27
MC=27X(1/18)=3/2
（2）AB:BM的值.
AB:BM=6:13.5=14:27
4、小明看一本课外读物,第一天看了全书的3分之1少1页,还剩下49页未看,那么,第二天应从第几页看起?
共有（49+1）÷（2/3）=75页
75x(1/3)=25
应从第25页开始
9、长方形的长为x+3,宽为5,它的面积小于20.求x的取值范围.
（x+3)x5＜20
0＜ x＜1
10、小杰、小明两人同时绕400米的环跑道行走,已知小杰比小明速度快,如果他们同时由同一点同向而行12分30秒首次相遇,如果他们同时从同一点起背向而行2分首次相遇,求小杰,小明两人每分钟各走多少米?
设小杰的速度是x米∕分,小明为y米∕分,由题可得：
(x-y)×12.5=400
（x＋y)×2=400
经计算可得：
x=116 y=84
11、计算：2的 100次方 – 2 的99次方 – 2 的98次方 – 2的 97次方 - … … - 2 的3次方 – 2的2次方 – 2 – 1
2的N+1次方=2*2的N次方,所以减到最后是《1》
12、已知∠ a的余角比∠a 的2倍还大15°,求a 的补角的度数.
解;设∠a=x
90-x=2x+15
x=35
a 的补角的度数为145°
13、把一个3个棱长为2厘米的正方体拼成一个长方体,求其表面积和体积.
只能并排拼,那就会有4个面被挡住,而一个正方形有6个面,3个就是18个面,所以只有14个面能看到,而一个面是2*2=4cm的平方,则表面积就是4*14=56cm的平方
一个正方形的体积是2*2*2=8cm的立方,三个正方形的体积即此长方形的体积=3*8=24cm的立方
14、计算：180°－（25°32′+ 62°18′）
=92°10′
15、甲、乙、丙三人同时从同一地点O出发,甲沿北偏东30°方向走了4千米 到达A地,乙沿南偏西30°方向走了3千米到达B地,丙沿南偏东60°方向走了3千米到达C地.取1cm表示1千米,在纸上描出A、B、C三地的点.
这道题 你自己画吧
在纸上画一个直角坐标系
要标明度数呦
16、已知x是相反数等于它本身的数,y是最大的负整数,求 xy+x分之y+3x+2y的值
x=0 y=-1 值为=-2
17、某部队一次行军训练,限定3.5小时内完成,其间休息15分钟,去时的速度是每小时7千米,回来时的速度是每小时6千米,问队伍最远走多少千米就得返回?
设x千米必须返回,(x/7)+15/60+(x/6)≤3.5 ,
解得 x=10.5（千米）.
